When my son was growing up, I was always guilty, no matter what I did. Make decisions and be happy with the decisions you've made. I tell myself, in the long run, it's the love, the quality of relationships that you have with your family, your friends and giving back to the community that matters.

I don't like the word 'balance.' To me, that somehow conjures up conflict between work and family... as long as we think of these things as conflicting, we will never have happiness. True happiness comes from integration... of work, family, self, community.

Tech is all about building human connections.

People remember my last name because it's different, and people remember me in meetings because I dress differently from other people just because I'm a woman. Those kinds of things give you an opportunity and a spotlight, so use that to your advantage. Use it as a platform to demonstrate your knowledge and your capabilities.

About half my work in education is U.S. political reform around school districts and charter schools, and creating more room for entrepreneurial organizations to develop. And about half on technology, which I look at as a global platform.

On telly, there's been a move towards entertainment - with some very high-powered, fast-moving dramas. Then we have the Internet, where we get our information but it's all in bite-size pieces. I think the documentary, as a form, actually speaks to what's missing.

Digital currencies present a chance for money to truly become information, and for the creation of a global financial system that is truly frictionless, open, and uncensored - the vision we once had for the Internet.

When I made 'Eight Below,' they wanted me to shoot digital, and I didn't want to do it because that's just what I need, to get a great series of takes and then find out the camera was frozen.
